Resources Technical Review - Analysis of ToughMet® 3 and Cu-14Ni-3Al Technical Reviews offer detailed comparisons of Materion products to competitor materials. ToughMet 3 and Cu-14Ni-3Al are both high strength copper alloys commonly used in the marine and oil and gas industries, but significant differences are realized when their properties are compared. This Technical Review discusses those differences that make ToughMet an advantageous replacement for the nickel bronze alloy in demanding applications and severe environments. Charpy V Notch Behavior of ToughMet 3 Materion tests the CVN impact strength of its materials in accordance with ASTM E-23 with a Type A specimen. Tech Brief - Galling Resistance of 25 Alloy and ToughMet 3® when Self Mated and Mated with Various Metals Galling resistance has been one of the primary reasons that Alloy 25 and ToughMet have been selected for equipment where the service conditions included high strength and relative motion between metal components. Alloy 25 and ToughMet are shown to resist galling to many other metals and to resist galling to other Alloy 25 parts and ToughMet parts. Tech Brief - Cavitation Resistance of Selected Copper Alloys Materion Performance Alloys ToughMet® and copper beryllium products are highly resistant to cavitation. Galling of Non-Magnetic Drill String Components Copper beryllium is the most resistant to galling and seizing of all metals used in the drill string, and inherently provide all the galling and seizing resistance for the life of the component. Temperature Dependence of Tensile Properties for Various Alloys The temperature dependence of the tensile properties for various tempers of ToughMet 3 (C72900), Alloy 25 (C17200) and Alloy 3 (C17510) rod were measured from -195 °C (-320 °F) to 345 °C (650 °F) in accordance with ASTM E21. Anti-friction Behavior Of Copper-based Bearing Alloys In a representative test for coefficient of friction, copper beryllium and ToughMet® alloys showed a favorable combination of high strength and low friction. Tech Brief - A Guide to Galvanic Corrosion Galvanic can occur when two or more dissimilar metals contact each other in an electrolytic environment. This can occur in seawater, chemical processing, or in automotive fasteners and connectors exposed to road salt spray. It is important to understand the relative position of metals on the galvanic series when they will be coupled near an electrolytic solution. Galling Resistance Of ToughMet 2 Alloy The exceptional galling resistance of ToughMet® 2 and other copper alloys for wear plate applications is explored in this technical paper. Machining Recommendations For ToughMet Rod, Tube and Plate The machining recommendations (turning, milling, drilling, tapping, grinding and sawing) for ToughMet® 3 AT and CX tempers of rod, tube and plate alloys are discussed in this technical brief. Enhancing ToughMet® 3 Bearing Performance with Metalife Hard Coated Steel In comparative sleeve bearing tests against a hardened steel shaft, ToughMet showed unprecedented performance for a metallic bearing material and its properties can be enhanced when coupled to steel that has been hard coated and polymer impregnated. Stability of Copper Alloys at Elevated Temperatures Detailed charts displaying the room temperature properties of copper beryllium and ToughMet alloys after exposure to elevated temperature. ToughMet Plain Bearing Performance with High PV This technical brief demonstrates that ToughMet® plain PV limits can be significantly higher than other bearing alloys, including popular cast manganese and aluminum bronzes, particularly at heavy loads.
